Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesUsing the James Webb Space Telescope, astronomers have peered back 13 billion years to discover surprisingly lonely supermassive black hole-powered quasars. g.
Supermassive black holes are believed to lurk at the hearts of all large galaxies in the relatively modern universe. Because no star is large enough to collapse and black holes with such monstrous masses, scientists know supermassive black holes must form in different ways than so-called"stellar-mass black holes" with masses between 10 and 100 times that of the sun, born from the deaths
"It's just phenomenal that we now have a telescope that can capture light from 13 billion years ago in so much detail," Eilers said."For the first time, JWST enabled us to look at the environment of these quasars, where they grew up, and what their neighborhood was like."To investigate the wider surroundings of quasars, the team selected five supermassive black hole-powered regions studied by the JWST between August 2022 and June 2023.
"The cosmic web of dark matter is a solid prediction of our cosmological model of the universe, and it can be described in detail using numerical simulations," team leader Elia Pizzati, a graduate student at Leiden University, said in the statement."By comparing our observations to these simulations, we can determine where in the cosmic web quasars are located.")
